Fatigue, stress and anxiety: why you feel constantly drained
Imaad Karim, Naturopath / 9 min read / Updated September 2026
Feeling exhausted has become so common that many people have decided it is simply part of modern life.
You wake tired despite a night that should have been enough. By mid-morning you are relying on coffee to get through, and by the afternoon even simple tasks feel like more than you have. You might be irritable, struggling to concentrate, or lying awake at night with a mind that will not slow down.
Occasional stress and tiredness are a normal part of life. Ongoing fatigue, chronic stress and anxiety are worth looking at properly. These symptoms overlap constantly, and together they often suggest the body and mind have been carrying more strain than they have had the chance to recover from.
My approach is holistic and evidence-informed. Rather than managing the symptom on its own, I look for the factors that may be contributing to how you feel, and I work alongside your GP and other health professionals where that is appropriate.
Understanding stress
Stress is the body’s natural response to a challenge or a perceived threat. In the short term it is useful: it keeps you alert and helps you respond to a demanding situation. When stress becomes ongoing, though, the body gets fewer and fewer opportunities to recover.
The role of the nervous system
The autonomic nervous system runs the things you never think about: heart rate, breathing, digestion, blood pressure. It has two branches, and a healthy system moves between them as needed.
Fight or flight
Adrenaline and cortisol are released so you can respond to what is in front of you.
- Increased heart rate and blood pressure
- Heightened alertness
- More energy made available
- Digestion dialled down
- Non-essential functions temporarily suppressed
Useful in the short term. Prolonged activation puts strain on multiple body systems.
Rest and digest
The branch responsible for recovery, and the one chronic stress makes hardest to get back to.
- Heart rate slows
- Digestion works properly again
- Restful sleep becomes possible
- Nutrients are absorbed
- Immune function and tissue repair are supported
Much of what I do is aimed at making this state easier to reach again.
Understanding anxiety
Anxiety is a normal emotion. It helps us respond to uncertainty. When worry becomes persistent, or starts interfering with ordinary life, it deserves proper assessment rather than being pushed through.
It shows up in the body as much as the mind, which is part of why people arrive describing physical symptoms first:
- Racing heart
- Muscle tension
- Restlessness
- Trouble concentrating
- Poor sleep
- Digestive discomfort
- Excessive worrying
- Constantly on edge
Because anxiety and chronic stress activate similar physiological pathways, they very often turn up together.
Common contributing factors
Fatigue, stress and anxiety rarely have a single cause. More often they build out of a combination of physical, psychological and lifestyle factors.
Poor sleep
Quality sleep is where physical recovery, hormone regulation and nervous-system balance happen. Poor sleep feeds back into fatigue, concentration, resilience and inflammation, which is why it is one of the first things I ask about in detail.
Nutrient status
Energy production and nervous-system function both depend on adequate nutrition. These are the ones most commonly involved:
| Nutrient | What it supports |
|---|---|
Blood sugar regulation
Skipping meals, or running the day on refined carbohydrates, sugary snacks and caffeine, contributes to blood sugar swinging around. That shows up as energy crashes, irritability, poor concentration and a growing reliance on stimulants to get through the afternoon.
Balanced meals containing protein, fibre and healthy fats can help support steadier energy across the day. This is usually the least glamorous part of a plan and one of the most useful.
How naturopathy can help
My goal in a consultation is to understand the individual rather than the symptom. An initial consultation runs a full hour, and includes a comprehensive assessment of your:
- Medical history
- Diet and nutrition
- Lifestyle habits
- Sleep quality
- Stress levels
- Current medications
- Any available pathology results
Where it is appropriate, I may also recommend further investigation in collaboration with your GP, through accredited laboratories, and only where the result would genuinely change the plan.
Herbal medicine and nutritional medicine
One of the strengths of naturopathic care is being able to use both, for two different jobs.
Nutritional medicine
Focused on making sure the body has what it needs to function. Where deficiencies or increased requirements are identified, targeted nutritional support may help restore those foundations.
Herbal medicine
Rather than replacing nutrients, herbs may be selected to support healthy nervous-system function, promote relaxation, assist sleep quality, and support the body’s ability to adapt through stressful periods.
Used together, nutritional medicine provides the building blocks the body requires, while herbal medicine supports normal physiological processes and recovery.
A personalised approach
No two people experience fatigue, stress or anxiety in the same way. Two people can describe almost identical symptoms and have entirely different things underneath them. One may have an iron deficiency. Another may be carrying chronic stress, broken sleep, or blood sugar that swings all day.
That is the reason a consultation looks at the whole person. Considering nutrition, lifestyle, medical history and pathology findings together is what makes a plan specific to you rather than generic.
Take the first step
Feeling constantly exhausted, overwhelmed or anxious is not something you simply have to accept. Understanding what is contributing to it is what makes a personalised plan possible.
